Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction of a metal insert nylon traveler.

In order to further improve the all-nylon traveler and improve the abrasion resistance of the thread passage section, a nylon traveler using a metal insert was developed, and its effects are remarkable.

However, since the wear of the resin part affects the life of the traveler, the quality of the material and heat treatment have improved rapidly in recent years, and this imbalance has been resolved.

With the above structure, the wear resistance of both the metal insert and the resin part has been improved, but on the other hand, as the hardness increases, the toughness of the traveler is lost, and there is a drawback that the traveler breaks when the opening size is pushed wide when attached to a ring.

In order to prevent this, it has been considered to increase the opening size, but this has the disadvantage that it may come off the ring during spinning and cause scattering.

The present invention provides a traveler that eliminates these drawbacks, and examples thereof will be described below with reference to the drawings.

As shown in Fig. 1, in a metal insert traveler in which a head 1 made of synthetic resin and a leg 2 are connected by a wear-resistant metal insert 3, the head 1 made of synthetic resin has an approximately U-shape. One end of the metal insert bent into a shape is buried, and a through hole 5 formed vertically in the longitudinal direction of the synthetic resin leg 2 is inserted into the vertical portion 4 of the metal insert, so that it can freely move up and down and left and right. , and the other end 6 of the U-shaped metal insert
The tip is bent upward and inserted into and removably inserted into the hole 8 provided on the lower surface of the tip 7 of the leg 2 to form a metal insert traveler for a spinning machine.

With the above configuration, when attaching the traveler to the ring, as shown in FIGS. 2 and 3, the leg portion 2 is lifted up to the upper blade, the direction of the leg tip 7 is changed to the right or left, and By lowering the leg portion 2, it can be easily attached to the ring regardless of the opening size.

Therefore, there is no breakage of the traveler or difficulty in the work, which is caused by forcibly pushing the traveler apart in the vertical direction when attaching the ring, as in the prior art.

Also, all the force (F') applied during spinning is directed outward, and the force (F') applied to the leg 2
Since the other end 4 of the U-shaped metal insert 3 is fitted into the resin part, it is possible to completely prevent the metal insert from coming off.

As described above, the present invention has the remarkable effect of making it extremely easy to attach a metal insert nylon traveler to a ring, which was difficult in the past, and preventing breakage and detachment due to attachment.

Claims (1)

[Claims] 1. In a metal insert traveler in which a synthetic resin head and legs are connected by a wear-resistant metal insert, one end of the metal insert bent into a substantially U-shape is buried in the synthetic resin head. , a through hole provided vertically in the longitudinal direction of the synthetic resin leg is inserted into the vertical part of the metal insert, so that it can be freely moved up and down and left and right, and the tip of the other end of the U-shaped metal insert. A metal insert traveler for a spinning machine, characterized in that the metal insert traveler is bent upward and is removably inserted into a hole provided on the lower surface of the leg end of the synthetic resin leg.
